The Prophet ﷺ was commanded to prostrate on seven bones and was forbidden from gathering up his hair or clothing. He prostrated on his hands, knees, and the tips of his toes.Sufyan said, Ibn Tawus said to us, while placing his hands on his forehead and running them down to his nose, "This counts as one."The wording is that of Muhammad.
أخبرنا محمد بن منصور المكي وعبد الله بن محمد بن عبد الرحمن الزهري قالا حدثنا سفيان عن ابن طاوس عن أبيه
أمر النبي ﷺ أن يسجد على سبع ونهي أن يكفت الشعر والثياب على يديه وركبتيه وأطراف أصابعه قال سفيان قال لنا ابن طاوس ووضع يديه على جبهته وأمرها على أنفه قال هذا واحد واللفظ لمحمد
